The nucleotide sequences of 5S rRNAs from three ciliated protozoa, Paramecium tetraurelia, Tetrahymena thermophila and Blepharisma japonicum have been determined. All of them are 120 nucleotides long and the sequence of probable tRNA binding site of position 41-44 is GAAC which is characteristic of the plant 5S rRNAs. The sequence similarity percents are 87% (Paramecium/Tetrahymena), 86% (Paramecium/Blepharisma) and 79% (Tetrahymena/Blepharisma), suggesting a close relationship of these three ciliates.
